Original air date: September 02, 1993. Jim Keith wrote two very interesting books that discuss black helicopters: Black Helicopters Over America: Strikeforce for the New World Order (1995), and Black Helicopters II: The End Game Strategy (1998). Media attention to black helicopters increased in February 1995, when first-term Republican northern Idaho Representative Helen Chenoweth charged that armed federal agents were landing black helicopters on Idaho ranchers' property to enforce the Endangered Species Act. "I have never seen them," Chenoweth said in an interview in The New York Times. "But enough people in my district have become concerned that I can't just ignore it. We do have some proof."The black helicopters theory resonates well with the belief held by some in the militia movement that troops from the United Nations might invade the United States. The John Birch Society published an article in The New American detailing how the existence of the covert aircraft was mostly the product of possible visual errors and a tendency towards overabundant caution.
